Freeze Dryer Vacuum Pump Comparison (Oil Less, Premier, Standard) -- HARVESTRIGHT

[@thefreezedryingcommunity]

There are so many variables in choosing the right pump for your situation. I hope that I was able to answer any questions you may have in purchasing the correct pump.

[@ragusaf]

Goood video. i was hoping to see a review of their new oilless pump. hopefully you get one of those soon :-)

[@Clbind]

When you said you had two of the premier pump is that because it didn’t last?

[@thefreezedryingcommunity]

@@Clbind No. I have a premier pump for each of my freeze dryers

[@jimsember3528]

I called Harvest Right to ask them about the life of each pump. Spencer told me that, on an equivalent use basis, the oil-less pump would need that $350 rebuild every 2 years. That is because without oil lubrication, the pump elements wear out faster. The standard pump would last about 5 years and the Premier would last 7+. He also told me that he used to work in their service group and the Premier pumps had far fewer issues. This nailed it for me. I ordered mine with the Premier pump.

[@Elev8minh]

Thank you sir for this valuable information you provided!!!

[@keithhogan6997]

Thank you! The cost of the rebuild and approx expected interval between services was sorely lacking in the comparison. I do my own fluid services on my personal vehicles & equipment so doing it on the pump wouldn't be foreign. And to be quite honest with YT it is so so simple to learn. I will be going with the Premier as well. Thank you again!

[@BobBob-il2ku]

Like most things it seems like the middle Of the road is where the value is ie the premier pump

[@pokerstar81]

Thanks I may go with oil but I like the no oil changes

[@bevs9995]

but how much oil? And at what cost?

[@airlar4857]

Good news: you don't have to remind yourself to change the oil on the newer units... newer firmware seems to have a timer and prompts oil changes for each of the various pumps 👍

[@bennierocks5408]

Do you have a video on how to do the oil changes on the two pumps?

[@dsbennett]

I have a friend who is a Research & Development engineer. He works with all sorts of equipment, including vacuum pumps. He came over to see my medium freeze-dryer and Premier pump. He couldn't believe the pump was running because it had about the same level noise as the freeze dryer. He was accustomed to vacuum pumps being extremely loud. I'm running my 10th load right now and the oil looks crystal clear. HINT: Before buying any complex item, you can download the owner's manual online and see what you will be faced with if you buy it. That's why I went for the Premier pump over the others. Changing/filtering the oil is easy and fast and you'll probably have to do it around once a month. No big deal.

[@zita-lein]

I haven't bought my freeze dryer yet, so this video, like many others, is like gold. Thanks so much!

Ma'am please call HR ask about the WARRANTY what is covered and will a service men come to YOUR HOME for repairs. I hope your handy because YOU ARE THE SERVICEMAN. Tech support will diagnose the issue but YOU have to make the repairs. It's not all bad but your 3 year warranty only covers tech support and MAYBE some parts ! Do due diligence and ASK lots of Questions.

[@lindapeterson3483]

When I was ordering my FD in March, I asked about the maintenance on the oil less pump and HR told me they recommend the pump be sent back to the company every 2-3 years to replace bearings and some other things. The cost of the maintenance is $350, plus I assume I’d have to pay for shipping both ways. Since I don’t have another pump, I’d be without for who-knows-how-long? I was going to order the oil less, but after that conversation I opted for the Premier and am very happy with it.

Suggestion for future video: You've several times hinted that commercial operations may require oil-less pumps. This begs the question: Why? Is there a risk to the food with oil pumps?

[@jimmyart3446]

I was looking for explanation of fog premier pump makes. At first I was shocked with amount of fog or mist in my garage. I thought, one day my garage will blow-up. Now I know, it's not a oil fog, but water... Thank you excellent video

[@airlar4857]

I had the same issue with fog - the HR tech i spoke with suggested it was oil, but that it was harmless. In either case it's not going to explode 😂

[@bbrnkyle74]

Make sure you don't overfill the pump. If it's above half while running it will generate more (fog). I generally fill to half, start pump, and top off to just below half as the oil level will drop at startup. Hope this helps.

[@keithhogan6997]

While I haven't bought one yet I don't see why I can't get the "fog" to be directed into a DIY filter chamber to eliminate it as much as possible, if not be able to get it to exhaust to the outside environment.

Great job. Most of the info did not come as a huge surprise except for: I was surprised to learn that the cheapest pump was the quickest to get under pressure --- and that the oil-less took the longest.

[@airlar4857]

Difference in speed to reach vacuum pressure is virtually irrelevant when you consider the average time to run a batch is 24 hours or more. I'd think the base pump is best for folks with a limited budget, premier has the best longevity/reliability with minimal maintenance (this according to the Harvest Right techs i spoke with). IMHO I wouldn't get an oil free pump without a backup pump - the rebuilds aren't cheap either

[@eviebays]

first of all thank you for all your research and video's. I have learned tons. so, I messed up my standard pump, after only 31 loads. and needed a new one. did lots of research and decided to bite the Bullitt , on the premier pump also. when I went to the Harvest right web sight, I couldn't find the stile you have. but the one they had, had a different face and the description was the same. I found no other specs on it. I wondered if it was still 7 cfm and 3/4 hp. it looked smaller. did extensive search, and even called the office where you order. asking why the body had changed. but of course had to wait for the teck help to call. got impatient and ordered the one on the accessories list. thinking must be the same with the same description , also no other option . anyway. when it arrived, I was shocked to find it was ONLY 5 CFM AND 1/2 HP. so I called again. did not wont this smaller pump for the same price of the 7CFM . why was the price the same. and why no details about the lower cubic feet per inch. and HP. again, the sales office knew nothing about the 5 cfm pump. and transferred me to a teck again. and they gave me a message, they would get to me in 24 hours. i have been weighting a week, for the first thing on the old pump. just a heads up, this primer pump is not the same power as the original. it is much slower drawing air . just not happy at all. now it is a 3 day Holliday, of course. have wasted so much time and $$$ I am hopeful, of fixing all this. but now, I'm not happy should have just got another standard pump. almost 3 times cheaper and pulls more air is a much shorter time

[@thereloaderscloset9096]

[@mikeklingler9659]

The new premier pump is not the same as the original premier pump. They have gone to a cheaper model but still sell it as the “premier pump”. I have the original Premier Pump, it is great. I’ve had it over two years and it’s still going strong. My friend bought a freeze dryer and purchased the “Premier Pump” with his freeze dryer. He got the new style pump, it worked fine for several batches, then he had problems 3 months into his purchase. Turns out his not so “premier pump“ had failed. He got a replacement. The new one was bad out of the box. He got another replacement it was bad out of the box as well. After several weeks, he is still trying to get a resolution. In testing, we attached my Premier Pump to his freeze dryer and it works great. The local store he bought his unit from, who has been very helpful and supportive, I might add, said he has had many of the new style pumps not work, right out of the box. He is currently working with HarvestRight to get a solution for all of these folks who have got the newer, not so premier pump, but paid for the premier pump. They are down, while they figure out a solution. HarvestRight is really losing its reputation. They are growing much faster in sales than in support and in their ability to test new product before they start selling them. Their support was so good when I bought mine. Now they seem to be in a support tail spin. So sad! I hope they survive the growth!

I bought the large freeze dryer and it came with the standard pump. I got tired of dealing with oil changes and then ordered the oil-less pump. I've been using it for about two years now with no issues. He is right that the pump spits out a blast of black water droplets on startup, but that only seems to happen if the door or drain valve is open. Once you close it all up and start the vacuum, it starts off noisy, but then the noise level drops considerably. The oil-less pump is very strong. Several times I've seen it pull down to under 100 mTorr on my large freeze dryer.

I fixed the oil mist coming off the Premier pump, I found occasionally a little oil drips out the top near the cap, then burns while the pump is running. My solution was plug a short thick extension cord into back of freeze dryer, then plug the vacuum pump and a cheap Ebay/Kijiji 3M air filter into that. So whenever the pump runs, the 3M air filter runs, I believe cools off the pump and removes 100% of the oil mist. I have a cheap $20 "3M Office Air cleaner", I can cut a regular house furnace filter in half and stick it into the air cleaner.

The oil/water mist in the air with this pump is a serious issue, IMO. This happens every batch with mine. And this is in a well ventliated 400 square foot detached garage! I can't see how I could ever run this in the house. There is clearly enough oil in the mist that I can smell it.

[@theoldguy9329]

I have what I think is now standard after the J&B (? no longer sold broke down). From the old one I filter after every batch. I change oil every second I cleaning...maybe after 79 loads per cleaning. There is not a lot to clean I presume because the filtering does a good job on the oil. When I filter there is a bit of a lip on the Harvey-like HR filter (now with cotton) where the water and some dirt accumulates and that I pull out with a baster. On "wet" loads I can get 2 ounces of water which I want out of the pump. If the premier is putting this out as an aerosol you will get a good fog. PS. I think on the standard, you get most of the water out if you raise the back of the machine.

[@ichetuknee]

I am glad to read @jimsember3528 's comment about the life span of the three types of vacuum pumps. To this, I would add that one could purchase many cases of vacuum pump oil (grade 19 or higher) for the price difference between the premier and the oil-less pump. So, I went with the premier on all three of our large freeze driers. I enthusiastically encourage others to invest in a Harvest Right freeze dryer and use it to pack away as much food as you can before inflation makes it impossible to afford food. Helpful hints: By plugging the vacuum into another outlet, so that it is manually controlled (rather than controlled by the software and the freeze dryer's outlet); you can start the vacuum immediately upon closing the chamber. This begins the water evaporation process immediately, thereby lowering the temperature more rapidly (as evaporating water absorbs heat) and reducing the freeze drying time by several (around 6) hours per load. This works very well with non-liquids on the trays. (I made a big mess with unfrozen pureed bananas, though. The bananas were so liquidy, that they began boiling - all over the chamber.) We pre-freeze our loads in our freezer, in order to reduce the time required to lower the chamber temperature before the drying process can begin. Using extra trays, we process everything a few days in advance, load the trays, and put it in the freezer. Frozen meats, vegetables, fruits, cheeses, etc. all do well. When one load comes out, we bag it, use warm water to rinse out the ice, while cleaning the chamber, and get another load going in less than 30 minutes. Our freeze dryers experience very little down time. Running a vented PVC drain line from each unit to the garden allows for good use of the water, as well as avoiding the need for lugging buckets of drain water. Venting the PVC drain line, with vents pointing upward as water runs downward, prevents water from being sucked back into the chamber upon opening the line.

[@kellynightingale]

I was unsure which size and pump I should get. Medium or Large? I was thinking medium just because of the outlet situation. Then premiere pump or oil free? Any additional thoughts you could provide. Also do you get your oil from Harvest Right?

[@ichetuknee]

@@kellynightingale My recommendation is to stick with the premier pump. The pump size isn't the issue, inasmuch as we are only trying to reduce chamber pressure to less than 500 micro-Torr. Oil/oilless is the real choice. Again, stick with the oil. Harvest Right specifies any of three brands of approved class 19 oils, in order to avoid voiding of warranty. After the warranty elapses, any brand of class 19 or higher vacuum oil is acceptable. Buy yourself a case or two of oil now, while it is available and cheap. It will be hard to get and considerably more expensive in a few years. You may, but do not need to get the oil from Harvest Right.

HR no longer ships units with the door pad - too many instances of them interfering with the seal. Dollars to donuts the difference is negligible since the door is 3/4" thick...

[@thefreezedryingcommunity]

Small benefit, not much. I have stopped using one. I will have a video coming out about it next week.

[@TFDchief-fk2sc]

What an awesome informative video! 👍🏼👍🏼

[@EarthlyVibes]

🇨🇦🇺🇸 you are soooo close to 100,000 subs. Thanks for the pump review

[@thefreezedryingcommunity]

Should get there today or tomorrow!😬

[@bigjermanprepared3164]

Does the oil have a shelf life in New condition, meaning how long can I store the oil in new condition. 🤔

[@charlottejustesen6375]

Thank you for bringing us this video

[@thefreezedryingcommunity]

You bet

[@rickssmokehouse4211]

Thanks bro I’d like to know the price of the reman on the oil less pump also the down time with reman. Ty God bless

[@thefreezedryingcommunity]

Down time will vary on demand i suppose. The rebuild as of right now is $350

[@keithhogan6997]

Jim Sember commented about speaking to Spencer at HR about the cost and service interval of the oil-less pump, with average use it would be about 2 years. With the Premier pump lasting approx 7+ years, and oil changes being a simple task, it has the best ROI. At least in my opinion.

Thank you

I have a question, would it be ok/ safe to have the freeze dryer in a bedroom ?

[@MaN-pw1bn]

I suppose you could run it anywhere that fit the criteria, but the constant background noise isn't good for you, if you have carpet, some water could be a problem, will it block egress/ingress routes in the event of an emergency, the heat put off by the pump might be an issue for a small room, you'd also have to run a fan which will just add to the noise, is there a dedicated circuit?? Those would be the first concerns that come to mind.

[@bigjermanprepared3164]

Great information thank you.

[@thefreezedryingcommunity]

Glad it was helpful!

[@MyTube4Utoo]

Very informative. Thank you.

[@emartin8907]

do you think i could run this in an apartment without pissing off my neighbors? I was even looking at rubber anti vibration mats and possible baffling panels..

[@flyingpaladin2712]

Excellent videos. I have watched many of them. Then I subscribed.

[@thefreezedryingcommunity]

Appreciate your support

[@traviswomack553]

I have the premier pump and it seems to run hot. Is this normal? 155 degrees or so, I can see the oil bubbling in the window. Is this normal? just doing my 4th cycle right now, so really new. Thanks

[@carlinbay]

I have been using the low profile oil less for 2 years and I am have problems so I am switching it out with the “eagle” oil less and trying to test the vacuum on the functional test. It has been running for 50 min and has only gotten to 1400 mt. Is that normal. Don’t I want it to get to 500 mt?

[@JohnMurse]

Thank you for this

[@roypase8488]

Oil recommendations for the premier?

[@thefreezedryingcommunity]

Robinair Premium or JB Black gold

[@thereloaderscloset9096]

So you keep stating in the vid that if the pump was bought from the original manufacture then it would cost more. Who is the OEM for the green Premier pump? As you read down the comments the new style/module is not the same and they are 1/2 HP and 5CFM. The larger pump would be nice to have. I really enjoy the vids.

[@rinab4405]

Question!!☝️ It's getting to spring harvest time here in North TX. Do I have to defrost EVERY TIME between batches? I do however change oil every batch. I have another batch waiting to be dried.

[@charadremur333]

I believe you only need to change the oil after like I thing 40 batches but don't quote me on that.

[@backyardrebuilds4068]

what is a mTor

[@PPCCO.]

This is the old oil less pump right?

[@resourcefulgirl]

I need your advice. I'm building a home and I'm trying to find the perfect location for my Harvest Right. The Premier Vacuum Pump still sounds too loud for my kitchen and open floor plan. The wall I'm planning on placing the Harvest Right on has the laundry room on the other side. If I put the pump in the laundry and made an opening to pull the hose through and kept the Harvest Right in the kitchen how much quieter would it be?

[@PatriotMango]

did you say we have to send the oiless in for maintenance every 3k hours?

[@thefreezedryingcommunity]

yep!

[@47retta]

Does the water fog that the premier pump puts out cause the room to start smelling?

[@thefreezedryingcommunity]

No smell that i have noticed

[@sandragonsoulindouglas8327]

What are the possible hazards of the oil less pump?

[@thefreezedryingcommunity]

It's loud, runs hot and needs a rebuild every 2000-3000 hours

[@annabanan5518]

Are these pumps interchangeable on the freeze dryers? If I go with the premier and decide to replace it, can I replace it with an oil free pump (and vice versa)?

[@makosandburger8668]

yes you can.

[@thefreezedryingcommunity]

Yes, as long as the pump is made for freeze drying. These pumps shed water from the oil. Not all vacuum pumps are designed to interact with water

[@jozy5154]

How long does the pump run? Does it run for hours

[@thefreezedryingcommunity]

runs for most of the cycle. 20-30 hours

[@jozy5154]

@@thefreezedryingcommunity I live in a apartment, I think it might be too loud for me and neighbors

[@silverbackag9790]

I don't know why they didn't make the premier pump 110/220 since it uses DC motor. Wouldn't have added much (if any) to the cost.

[@Jonathan-px9oz]

Thank you for saving us $1500+ dollars! Why would I pay more for a little less hassle when the oil free: Is way more expensive, has a shorter lifespan (and/or more upkeep costs), is WAY louder, and uses 50% more electricity?! And takes up more space! Thanks!

[@thefreezedryingcommunity]

Exactly!

[@Texas_Radical]

@@thefreezedryingcommunity Glad I did my homework on that one too. Also I spoke to one of the guys at HarvestRight and he told me the Pharmaceutical and lab models are NOT for food. the 8 tray was what I was going to buy but I plan on using mine solely for food so that was a no go.
